The Bushnell Professional Boresighter is an essential tool to quickly adjust the range or iron sights to line up with the barrel of your rifle or handgun. Correct use of this Boresighter will put test sights on the target, requiring only a minor expenditure of time and ammunition per test shot to reach zero at a given distance.
Because of the many variables involved in both the ammunition and the firearm itself, the final “aim” must be achieved by live firing.
Includes: Boresighter; 0.17 inch shaft; 0.22 to 0.27 inch shaft; 7 mm to 0.35 inch shaft; 0.35 to 0.45 inch shaft; carrying case; and paper instructions.
